I like to ask folks to read into it what they will, for me this says it was random until LFGP came along, but now it is looking like the last 5-7 years a new pattern of earlier arrivals, which led to my feeling that a Common could turn up any day prior to today's find...nice to have 2 as well.

There are many in July, but the trend of first passage date has come forward quite some amount since the 80's.
